Study magick and how it works to understand better, but the answer is physically no. Some say astrally yes, but the astral isn't a credible source. Magick is nature, so if it's not natural it cannot be done. Blessed Be.
The only form of shape shifting that is real, is shape shifting your state of mind. Many cultures have this form of shape shifting, and I myself have done it often. It is easy once you find out how. Again, this is shape shifter your state of awareness and how you think, not your physical shape or soul.
You should study either way before casting. The answer however is no physical shape-shifting can happen by magickal means as a result of the nature of magick. People do argue on other planes or 'mental shifting' I don't know much about that and view it more as a belief so research and draw your own conclusion there, but when it comes to a physical change by magick the answer is 99% of the time no. [The 1% is when a spell calls for a routine to go with the spell. Example a weight loss spell that needs to be coupled with an exercise routine.]
Nope sorry to say this to you about a thousand times as to other people. Shapeshifting is not possible! You can not altar or change your physical body in anyway. This is not fantasy magick.
Everything including bone is made of energy and with enough will, belief, and self understanding it is entirely possible. Skepticism completely defeats the purpose of believing in magic
Believing in such things are a mere fantasy and although it sounds fun, it just isn't possible as so many have said. It defies the laws of physics and magic must follow those laws too.
Luciferius, what you have written is absolute rubbish. Obviously you have no idea what magic actually is! You seem to be one of those who think anything is possible with magic.It isn't!
